This invention relates toa remote control sel lector device for governing the rselection of records to belplayed by an automatic phonograph or of stations to be heard through a pre-tuned radio, and `more particularly to a multi-prism selector device' having a panel showing a plurality of selections, whichpanel may be changed to offer to view va plurality. of panels in succession. f Selector devices for coin controlled remote control selection for the playing of vautomatic 2 orpressing a key. In this manner compactness of a single cylinder is partially retained and Wall areav is conserved without the sacrifice of legibility. The means for changing the panels is a panel changing key which also controls the playing of records or the tuning in of stations. Se-

v lector devices are usually installed in places of phonographs are known to the art. They comprise generally two types. One type employsl a cylinder which is successively rotated and automatically selects the `phonograph record to be played and exposes its title to View. In this type one title is exposed and it requires a considerable amount of manipulation to Yhave a` prospective user View all of the titles which maybe presented. This is time-,consuming and itis found that the amount of effort lrequired results inra decreased play of records, asv the user is apt to become tired of continually rotating asingle cylinder. v

The other `type of selectorknown to the art comprises a large panel 'in which a number` of selections, say 24, are presented to view `at once. Selection ismade by pressing a button opposite the desired selection. The inanimate presentation of a large number of titles does not arouse curiosity,` with the result that after a cursory 7glance at the panels and the playing of a selection or two, the user is apt to lose interest in the selector.

One object of this invention is to provide a selector of the panel type in which a smaller number of titles are exposed to View, thus economizing on wall space, with provision for'means for conveniently and rapidly changing the panel to present a new array of titles.

vAnother object of this invention .is to provide a selector which combines the advantageous features of both types of the aforementioned types- I and convenience of a two Wire circuit between the f control and the remotely situated controlled machine or instrument.

Other and further objects of thisy invention appear from the following description.

In general, this invention contemplates the will .provision for 24 selections by means of a panel showing 8 selections, which panel may be changed in a simple,`expeditious and convenient manner with no other effort than by turning a button amusement or of refreshment. Patrons of such places have idle hands. Most people twirl a glass by a stem, rearrange loose articles, play or toy with napkins or the like. The` pressing ofa program key of this invention produces a revolution of the title-bearing prisms, `resulting in an entire change of the panel, producing a new and interesting effect which attracts attention and is productive of use. The actual selection of a recordfto be played is made by means of a selec- Ation key and the use 0f a coin through a coin control device of any suitable design.

More particularly, referring now to the drawings, the assembly is mounted in a casing I I provided with l0 Windows, I2, I3, I4, I5, IB, Il, I8,

i9, 20,'and 2|. rJournalled -behind the windows there are 10 three-sided prisms, 22, 23, 24, 25, 26. zi, 2a, 29, at, and al. The prisms are formed at their inner ends with integral bevel gears 32, 33, 34, 35,36, 37, 38, 39, 40, and 4I, Fig. 3. A vertically extending shaft 42 is journalled in suitable bearings 43 and 44. Secured to the shaft are `four bevel gears, 45, 46, 4l, and 48, which vmesh bear the th, 13th, and 21st selections.

with and drive gears 32 and 31, 33 and 38, 34 and 39, and 35 and 40 respectively.v A spur gear 49 is formed on the lower portion of gear 41. This meshes with the teeth of a gear 50 secured to a drive shaft 5| journalled in bearings 52 and 53 as can be seen by reference to Fig. 2.

A support 55 is provided with la pair of bosses 58 and 51, as can be seen by reference to Fig. 4. Journalled in the bosses by means of shoulder screws 58, there is provided a pair ofidler gears 59 and 60. The idler gear 59 meshes with spur gear 6| formed adjacent bevel gear 35 on prism 25, and with spur gear 82 formed adjacent bevel gear 36 on prism 26 so that whenever gear 6| is operated by the actuation of shafts 5| and 42, gear 62 will also be operated but in the opposite direction. n Similarly, idler gear 60 meshes with spur gear 63 .formed adjacent bevel gear 40 on prism 30 and with spur gear 64 adjacent bevel gear 4|v on prism 3|. The arrangement is such that the rotation of the shaft 42 through gear 50 and spur gear 49 willrcause the prisms 22, 23, 24, and 25 to revolve in one direction, while the prisms 21, 28, 29, and 30 will revolve in the opposite direction. It will also be observed that the direction of rotation of prisms ,22, 23, 34, and 25 on one side of the panel is in a direction opposite from the direction of `rotation of prism 26. Similarly, prism 3| will revolve opposite to the direction of rotation of prisms 21, 28, 29, and 30. All the prisms will revolve Vupon the depressing Yof the panel-changing'key which effects the actuation of shaft 5| as will presently be described, with a very curious effect which attracts attention and induces patrons to operate the panelchanging key, making for increased use.

Each of the prisms is formed with both bevel and spur gears to make them interchangeable so that any prism can be used vin any of the positions. The gears are molded with the center line of the teeth on the radius of the circle in which they are disposed so'the alignment of the faces of the prisms becomes automatic. The prisms may be made of metal or molded from plastic, the co-radial teeth being aligned with the faces of the prisms. The prisms themselves have a sectional form of anequilateral triangle as can readily be seen by reference to Fig. 2, though it is to beunderstood that any suitable polygonal form may be employed. Each of the faces is bounded along its longitudinal edges by inturned `flanges 65 forming grooves which serve to retain the upper and lower edges of program slips 68 while exposing their faces. Each of the prisms is provided with an axle 66. Adjacent each end of the axle is provided a portion of reduced cross sectional area .61 serving to .space the prism ends away -from the frame thus reducing friction. The inner ends of each of the axles are supported in a series of brackets similar to brackets Y1.3 and Wand s hOWn in Fig. 3 at 69, 10, 1|, 12, 13,

and 14. These are formed with 0r attached to frame l The panel as shown is adapted to expose 24 selections, 8 of which are shown by one panel. Prism 22 will bear selections 1, 9, and 17. Prism 23 will bear selections 2, 10, .and 18. Prism 24 will bear selections 3, 11,r and 19. Prism 25 will bear the 4th, 12th, and 20th selections. Prism 21 will Prism 2.8 will bear the 6th, 14th, and 22nd selections. Prism 29 will carry -the '1th, 15th, and 23rd selections, while prism 30 will carry the 8th, 16th, and 24th selections. Adjacent the bottom of the 'frame there is provided a plurality of selector keys 15,V 16, 11, 18, 19, 80, 8|, and 82. As can be panel-changing key 83.

seen by reference to Fig. 1, selectors keys 15, 16, 11, and 18 are disposed on .one side of a central panel-changing key 83, While selector keys 19, 80, 8|, and 82 are disposed on the other side of the The prism 26 is adapted to bear a series of numbers identifying the selections. Its three surfaces will bear the numbers 1, 2, 3, and 4 on one face, the numbers 9, 10, l1. and 12 on another face, and the numbers 17, 18, 19, and 20 on the third face. The prism 3| will bear the numbers 5, 6, '1, and 8 on one face, the numbers 13, 14, 15, and 16 on a second face, and the numbers 21, 22, 23, and 24 on the third face. The arrangement is such that when the panel is changed the correct numbers will appear over the selector keys, each of the numbersl being positioned directly over a key. y

Upon opera-tion of the panel-changing key 83, each of the prisms will revolve 120 degrees through the actuation of shaft 5|. The pressing of the panel-changing vor program key 83 will bring contact point 84, Fig. 6, into contact with contact point 85 and complete a circuit which will be described hereinafter, through a solenoid 86 which isvshown in Figs. 4 and 5. The armature 81 is drawn -into the solenoid, pulling the draw bar 88 against the action of spring 89. A ratchet wheel 54 is mounted'on the shaft 5l. The draw bar 88 carries a stop 90. The removal of the stop 90 by the movement of the draw bar to the left in Fig. 4 leaves the ratchet' wheel 54 free to revolve. The draw bar 88 carries a pawl 9| pivoted on pin 92 and urged into engagement with the-teeth of the ratchet wheel by means of spring 93. Movement of the draw bar to the left causes the pawl to override the next tooth of the ratchet. Upon releasing the panel-changing key 83, the spring 94 will cause contact point 84 to be drawn away from contact point 85, opening the circuit through solenoid 86. The spring 89 will pull the draw'bar to the right, causing the pawl to revolve `the ratchet which is secured to shaft 5| through an angle of 60 degrees. At the same time the stop 90 will be positioned under one of the ratchet teeth, locking the ratchet between the pawl 9| and the stop 90, holding the prisms against accidental dislocation.

Referring now to Fig. 2, the shaft 5| is journalled in bearings 52 and '53, and is mounted parallel to the shaft 42. In addition to actuating the prisms, the shaft 5| carries a group cam 95 made of insulating material having 10 lobes. Six of the lobes in pairs in separate planes are angularly located 60 degrees apart and each occupies 521/2 degrees of circumference. The other 4 lobes are in coplanar pairs, one having twice the Width of the other, the combined angular length being degrees, of which the Wider occupies 50 degrees of the circumference.

Referring now to Figs. 7, 8, and 9, which are diagrammatic exploded views showing the position of the cam lobes for different positions of the prisms, lobes 96 and 91 are of the same dimension, while lobes 98 and 99 are the same. These 4 lobes are located in an uppermost plane as can be seen by reference to Fig. 2. The next 2 lobes, |00 and |0|, are located in a second plane. The next 2 lobes, |02 and |03, are equal and located in a third plane. The 9th and 10th lobes, |04 and |05, are located in the lowermost plane. Adjacent the uppermost cam lobes are a pair of switches H6' having contact points |06, |81, |08, and |09.'v Adjacent the 5th and 6th lobes on a second 'plane is a switch |11 having contact points ||0 and Adjacent the 7th and 8th lobes' is a. switch Hs having 'Contact points H2 V grees which would take place on the actuation of the program or panel-changing key moves the shaft 5| sixty degrees, bringing the cams into the position shown in Fig. 8.- In `this position one of the switches I|6 is closed, completing the circuit through contact points |05 and |01. Switch ||1 remains open while lobe i |03 closes the circuit through switch IIB, through contact I points |I2 and H3. Switch H9 is open. Revolving the shaft 5| another sixty degrees brings the cam into the vposition shown in Fig. 9 in which both switches ||6 have closed so that both circuits through contact points |06 and |01 and |08 and |00 are completed. lThe lobe |0| operates the switch I I1 to close the circuit through contact points H0 and |II. Switches ||8 and ||9 are open. A further movement of 60 degrees will bring the parts back to the position shown in Fig. 7 so that the opposite, cam lobes 96, 93, |00, |02, and |04 will complete a similar cycle. It will be observed in passing that the size of the spur gear wheels 50 and 'island ofthe bevel gears 45, 32, et cetera, is such that rotation of the spur wheel 50 through 60 degrees will `produce a rotation of the prisms 22, et cetera,` of 120 degrees. The switches H6, |1,.||6, and IE6 are supported by a pair of posts and |2| of insulating material from a supporting bracket |22 secured to a cross member |23 carried by the frame The functions of the switches will be later described in reference to Fig` `10. i

The selection keys 15, 16, 11, 18, 10, 80, 8I,'and 82 are each provided with a pair of fingers |24, Fig. 2, extending forwardly to provide reinforcement for theplastic covering of the keys. In the rightward down-turned side flange which extends below t'he finger there is provided a notch |25 astride a cross membery |26. The width of. the notch |25 is such that a key movement of approximatelyl degrees is permitted. The

ange terminates in a locking nose |21 which, y

when the key is depressed, engages a'bail |28 which is pivoted around shaft |29 as can readily be seen by reference to Fig. 2. The bail |28 is urged upwardly by meansk of springIS. Depression of a selection key engages the nose |21 with the bail |28 and in doing so depresses the bail free of the nose |21 of the engaged key, thus holding the key in depressed position, serving to show which selection has been chosen so the operator may be sure of his choice before paying his money. The depressing of the selection key will break the contact between contact points ISI and |32; In Fig. 2, a section through selection key 19 is shown. Similar contact points |33 and |34, Fig. 10, are provided for key 15, contact lpoints |35 and |36 are provided for key 16, and contact points |31 and |38 are provided for key 11. Contact points |39 and |40 are provided for key 18. Contact points |4| and |42 are provided for key 00. Contact points |43 and |44 are provided for key 8|. Contact points |45 and |46 are provided for key 02. Each of the keys is urged upwardly by means of a spring |41 as can be seen by reference to Fig. 2. yIt will be clear from the foregoing that one of the keys is always the drawings.

held in depressed condition by means ofthe bail |28. Pressing another key cams the bail downwardly, permitting the spring |41 to raise the key which previously was depressed. When vthe nose |21 ofthe key being depressed engages the bail H|23 it remains locked, showing the operator the` particular selection made. "i Referring now to Fig. l., a coin slot |43 connectf ing with the coin chute'l46, Fig. 2, provided, leading to-any suitable coin-actuated switch, shown y diagrammatically in Fig. 10 at |50. Any suitable coin-actuated switch may be employed as is well known tothe'art.

Again referring to Fig. 10, there is provided a small transformer I5|, the primary |52. of which is connected by conductors |53 and |54'to alighting feeder such as found in homes and places of amusement, ordinarily 110 volt 60 cycle'alternating current. The secondary winding |55 of the transformer is used to deliver any Fdesired voltage. The winding of the solenoid 86 and its armature B1 are shown in Fig. 10, adapted to; be energized from the secondary of the transformer through conductors |56 and |51 when the selector key 83 is operated to close the circuit through contact points84 and S5, thus changingthe'y panel by the ratchet mechanism and gearing described hereinabove.

r.ln the operation of the device, let us assume 'they panel selector is in the posiiton shown in The cams will be in the position as shown in Fig. 1. Let us assume further that selection 3 is chosen. Doing so the operator would press key.11, thus opening the circuit lthrough contact points |31 and |38 in Fig. 10. A coink is now paid and when yfalling from the conventional coin mechanism (not shown) will close switch |50. The closing of switch |50 completes the circuit from the secondary ofthe transformer through conductor |56, conducto?.` `|59,.conductor |60, switch |50, conductor |6|, conductor |62, the winding of locking relay magnet |63, through conductor |64 and conductor to the other side of the secondary |55. The energization of the electro-magnet |63 of the locking relay will'close switch |66, placing the motor |61 across thesecondary winding |55 through conductors |69, |16, |1I, and |12.

kThereupon current will flow from one side of the secondary through Vconductor |68, conductor |69, the motor winding, conductor |10, switch |66, conductor ill, andfconductor |12 to the other side of the secondary winding |55. At

fthe saine time the locking relay will close switch |13. Geared to the shaft of the motor |61 are two'Y revolving contact arms |14 and |16. Immedia'tely upon the closing of switch |66 the motor will revolve and contact arm |14 will make contact with conductor |11.y Current willthen flow from conductor |56 through vconductor |18, and conductor |10, contact armi14, conductor |11, 'conductor |66,` switch |13, conductor |8I, conductor' |62, through the winding |63 of the locking relay, and conductor |54 to the other side of the secondary. It will be observed that the locking relay is kept energized and the motor |61 will'keep running since the'relay will actuate .the motor switch |65, keeping it closed.

The selector arm y |16 is also driven by the motor and it will revolve (the revolution of the arms'v being in a clockwise direction). It will be seen that the revolving conducting arm' |16 will first sweep by contact pointk I 82, leading to switch |I 1,. Since the switch ||'|1 is open as can be seen by reference to Fig. 7, no current passes.l The arm |16 next encounters the first'segment |83 of a group of segments connected in parallel by conductor |84. These segments are segments |83, |85,`|86, |81, |88, |89, |90, and |9I, being eight in number. Conductor |84 of the rst group of segments is connected by conductor'I92 to one branch of switch |16. Since contact points |08 and |01 are separated, no current passes. The revolving contact arm |16 next encounters contact |93 connected by conductor |94 to the switch ||8. Since this switch is open, as can be seen by reference to Fig. 1, no current passes. The revolving conductor |16 makes contact with a series of segments |94, |95, |96, |91, |98, |99, 200, and 20|, connected in parallel by conductor 202. Conductor'202 is connected by conductor 203 to switch ||6 which, as can `be seen by reference to'Fig. '1, is open. Accordingly, no current passes from one side ofthe secondary |55 through conductor 204.

It will be observed that conductor 204 is connected by conductors 2|2 and 2|3 and 2l| to an alternating current responsive device 2| 4 located in the remote phonograph, the current returned being through conductor 2|5, condenser 2I6, battery 2|1, and conductor 2I0. Conductors 2I0 and 2|I may be of any suitable length and serve to connect the selector device to the remotely controlled phonograph. Conductor 2|0 is connected by conductor 2|8 and conductors 205 and 206 to the revolving arm |16.

The contact arm |16 leaves contact point 20| and makes contact with contact point 201. Current now iiows from the one side of the secondary |55 through conductors |65, 204, 2|2, 2|3, and 2| I, through the alternating current responsive device 2|4, conductor 2|5, condenser 2I6, battery 2|1, conductor 2| 0, conductor 2|8, conductor 205, conductor 206, contact arm |16, contact point 201, conductor 208, switch l I9, contact point II4, contact point I|5, conductor 209, .and conductor |58, to the other side of the secondary. It should be noted that contact points |82, |93, and 201 are elongated to insure that alternating current impulses shall include several cycles to prevent the revolving arm |16 from failing vto close the circuit due to reaching one of these contact points during the zero voltage period in the alternations.

, The selection device is one well known to the art and includes alternating and direct current responsive units, and wherein the device is conditioned for selection by an alternating current impulse, after which a series of D. C. impulses are then transmitted until a cessation of impulses acts as the mode of selection. This is used in dial telephones and many other instrumentalities known to the art.

The selection device having been conditioned by the alternating current impulse by passing over contact point 201, the selection arm |16 then makes contact with contact point 2|9, which is one of a series of contact points 220, 22|, 222, 223, 224, 225, and 226. It will be observed that contact arm |16 is connected .by conductor 2 I0 to one side of the battery 2 |1. Direct current now ows from battery 2|1 through conductor 2|0, conductor 218, conductor 205, conductor 206, contact arm |16, contact point 2|9, conductor 221, conductor 228, across switch points |34 and |33, through conductor 229, through a direct current responsive selection device 230, to the other side of the battery 2|1. The contact arm |16 then makes contact with conductor 220 and current will flow from the battery through the conducting arm |16, through Contact point 220, through conductor 230', through contact points |36 and |35, through conductor 23|, through contact points |34 and |33, conductor 229, and thence to the other side of the ba-ttery as described above, giving a second pulse to the direct current responsive device 230. It will be recalled that selector 11, or the third selector, was depressed. This breaks the contact between contact points |31 and |38. When the rotating arm |16 reaches contact point 22 I, the potential on arm |16 passes through contact point 22 I, to conductor 232, where it encounters an open circuit, no current owing, hence no impulse is transmitted through the direct current responsive device 230, and this cessation of impulses is the act of selec-tion. In the eighth selection, were that made, the operation just described would be repeated, contact point 222 being connected by conductcr233 to switch point |40. Similarly, contact'point 223 is connected by conductor 234 to switch point |32, contact point 224 being connected by conductor 235 to switch point |42, contact point 225 being connected by conductor 236 to switch point |44, and contact point 226 :being connected by conductor 231 to switch point |46.

It will be understood that after the motor |61 drives the contact arm |14 one full revolution, the circuit made by contact of the contact arm I 14 with circular conductor |11 is broken, thus releasing the holding relay and stopping the operation of the device in a position ready for the next selection.

Let us now assume as a second example of operation that the second panel is exposed to View. The panel will present the following appearance: The prisms 22, 23, 24, and 25 would bear the 9th, 10th, 11th, vand 12th selections respectively. The rprism 26 would bear the numbers 9, 10, 11, and 12 over selector keys 15, 16, 11, and 18. Prisms 21, 2.8, 29, and 30 would bear the 13th, 14th, 15th, and 16th selections respectively, while prism 3| would bear the numbers 13, 14, 15, and 16 over selector keys 19, 80, 8|, and 82 respectively. The cam lobes would be in the position shown in Fig. 8, in which one segment of switch I|6 would be in the position to close the circuit through contact points |06 and |01. Switch ||1 would be open, while switch I8 would be closed. Switch I I9 would likewise be open. Let us assume the third selector key 11 were again depressed, opening the circuit through switch points I 31 and With the parts in the position shown in Fig. 10, a coin is dropped through ,the coin slot |48 and the switch |50 is again closed to start the motor |61 as described hereinabove. The rotating contact arm |16y sweeps by contact |82. Since switch ||1 is open, no impulse is received. The arm then sweeps by the 8 contact points of segment |84, and since one segment of switch I|6 across contact points |08 and |09 is open, no impulses are received. The arm then encounters contact point |93. It will be observed that in the position shown in Fig. 8, switch IIB is closed, thus permitting alternating current to ow from one side of the secondary |55 of the transformer, through conductor 209, through switch |I8, through conductor |94, through contact point |93, through contact arm |16, through conductors 206, 205, 2|8, and 2|0, through battery 2|1, through condenser 2| 6, through conductor 2I5, through alternating current responsive device 2|4, through conductors 2||, 2|3, 2|2, 204,

9 and |65, to the other side of the secondary |55, thus conditioning the remote control device in a position to be responsive to direct current impulses. The rotating arm |16 then contacts the series of segments |94, |95, |96, |91, |98, |99, 200, and 20|, which are connected' in parallel by conductor 202. Conductor 202 is connected by conductor 203 to one segment of switch H6, and contact point |06. Contact point |06, however, is in contact with contact point |01, thus closing the circuit through conductori2|3 to .the direct current responsive device 230. Current will therefore flow upon each contact with one of the contact points of the segment 202, from the battery 2|1, through conductors 2|0, 2|8, 205, 206,L

and the conta-ct arm |16, through the closed switch points of switch I6, and through the direct current responsive device 230. A Series of eight impulses is thusreceived by the direct current responsive device as contact arm passes each of the eight contact points of the segment 202. In passing over contact point 201, no response is received since switch I9 is open. Direct current impulses, h-owever, are received by the direct current responsive device-when the contact arm |16 passes over contact points 2|9 and 220. No response is received when the contact arm contacts is presented which preserves the cheapness and convenience of a two wirel circuit, `while at the Sametime presenting` a panel exhibiting a plurality of titles.

While this invention has been described for a remo-te control to govern .the selectionof records to be played by an automatic phonograph, or stations to vbe heard through a pre-tuned radio, it will be clear to those skilled in the art that it may be used in a public address system tochoose the part of a ship tO-"which commands or` warnings are to be given, or adepartment or room -of a building in a factory or school for .transmitting information, or in other ,installations as may be desired. A compact mechanism which offers *a large number of selections is provided;4 f

It will likewise be clear to those `slrilled. in the I art that various changes may be made in detail contact point 22| because selector switch 11 is open and the circuit -is broken across contact points |31 and |38. Similarly, `no further pulses will be received due to the interrupted circuit when the contact arm passes over contact points 222, 223, 224, 225, and 226, and comes to a stop by the opening of the circuit when contact arm |14 rides free of circular conductor |11. The relays of the selection device are such that the receiving of no further impulses for an appreciable length of time performs the act of selection. This time interval is sufficiently long so the selection will not be made by the passing of the contact arm from the last contact of one 'of the series of eight contacts tothe first contact of the next series as for example in .passing from contact 20| to contact 2|9.

Wehen the panel presents the third view, that is, with selections 17=l to 24 inclusive, to view, the cams are in the posi-tion shown in Fig. 9, in which switch ||1 is closed, and switches l|8 and ||9 are open. In this position, as will be readily appreciated by reference to Fig. 10, the alternating current conditioning impulse is transmitted as soon as contact arm |16 passes over contact point |02. Sixteen impulses will then be received from the eight contact points of each of segments |84 and 202 so that the selector keys will control selections 11 to 24 respectively in a manner similar to that just described.

It will be seen that this invention accomplishes the objects thereof. There is provided a selector of the panel type in which a number of titles are exposed to View, thus economizing wall space, with provision for means f-o-r c-onveniently and rapidly changing the panel to present a new array of titles. The selector of this invention combines the advantageous features of the cylinder type of selector in which only one title `is exposed'to view in the economy of wall space, and at the same time doesnt make the selection burdensome on the user. There is retained, however, the curiosity arousing feature. andthe feature which takes advantage of the tactile sense rof a user. The panel may be changed withoutl the use of coins and a user is certain by means of the` depressed key which selection he hasgmade before paying his coin. A multi-selection-device with-out departing from the spiritof this invention.
